解决报错ERROR: Service 'web' failed to build: Get https://registry-1.docker.io/v2/library/pyt...

一、问题描述

当我用docker-compose up时，因为需要build Dockerfile文件，出现下面这个错误：

ERROR: Service 'web' failed to build: Get https://registry-1.docker.io/v2/library/python/manifests/2.7: net/http: TLS handshake timeout

二、问题解决

1、查看可用的ip地址

[root@docker-node1 compose-flask]# dig @114.114.114.114 registry-1.docker.io

; <<>> DiG 9.9.4-RedHat-9.9.4-37.el7 <<>> @114.114.114.114 registry-1.docker.io

通过dig @114.114.114.114 registry-1.docker.io命令查看所有的可用地址。

2、修改/etc/hosts文件

可以将上述可用的ip以下面这种方式写入：

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

#写入可用的ip
34.199.40.84 registry-1.docker.io
34.201.196.144 registry-1.docker.io

然后进行文件保存，重新执行docker-compose up命令，问题解决。
